Research

Research is not a department. It is the company.

SONA is building a permanent research institution where scientific discovery continuously produces the next generation of medical technology.

Active programs

What we are working on.

  • PR01

    Non-contact physiological measurement

    Estimating cardiac, respiratory, and thermal signals without contact, and characterizing the conditions under which those estimates remain reliable.

  • PR02

    Individualized baseline modeling

    Building per-person physiological models that describe normal variation and detect meaningful departures from it.

  • PR03

    Multimodal fusion

    Combining optical, thermal, acoustic, radar, and environmental measurements into a single coherent representation of state.

  • PR04

    Closed-loop response

    Investigating whether controlled non-invasive stimuli can produce measurable, reproducible physiological change.

Stimulation research

Frequency-based stimulation research

SONA is researching whether precisely controlled acoustic or vibroacoustic stimulation can produce reproducible changes in measurable physiological states.
